To @ZZ whom t may concern: j

Be it' known that I, FRANK DILLON, a citizen of the United States, residing at Spiceland, in the county of Henry and State of Indiana, have invented new and useful Improvements in Shade Rollers, ofwhich the following is a specification.

This invention relates toa shade roller, of the type described in United States Patent No. 840,682, the broad object being to provide improved means for effecting engagement between the spring trunnion and the roller, without employing the gravity pawl described and claimed in the aforesaid patent.

A further object is to provide, in connection with a spring trunnion apertured transversely, a pin slidable through the aperture and designed to engage the lugs projecting from the inner portion of the adjacent end cap, the pin being of such length that it may be caused to slide out of engagement and free the lugs, for permitting the winding or unwinding of the shade.

A still further object is to provide a device of this character in which the engaging devices operate directly from the trunnion, instead of from the shade roller to the trunnion.

l/Vith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described and claimed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings, Figure 1 shows the device in elevation, as applied to a window frame; Figure 2 is a detail view, in elevation and section, showing the end of the roller mounting the spring and engaging devices; Figure 3 is a section on line 3-3 of Figure 2; Figure 4 is a detail view of the locking and controlling devices, as they would appear looking from the right in Figure 1; Figure 5 shows the elements of Figure 4 in the position assumed after the operating arm of Figure 4 has been moved to the left for rotating the roller trunnion and releasing the locking pin by gravity; Figure 6 is a detail view in perspective showing an end member for the roller, with engaging devices thereon for cooperation with the locking pin.

The roller 10 is provided with a cap 11, having mounted centrally thereon a pin 12,

1921. Serial No. 469,891.

this pin being circular in cross section arid loosely mounted, or adapted to be mounted in the bracket 14 projecting from the rod 15.

VrIhis rod 15 is provided centrally with an operating element or handle 16, and at the other end'is a bracket' 17 having an elongated slot 18 therein.

The spring 2O on the shaft or rod 21 serves the usual purpose, the spring trun-A nion or end portion of the shaft being designated 22 and being provided with a transverse aperture 23. The flat end portion of this trunnion cooperates with the slot 18 in bracket 17.

The end cap 25 is provided with apertures for receiving the ends of the lugs referred to below, the lugs being headed as shown in Figure 2 and rigid with the cap. A pin 27 is loosely mounted in transverse aperture 28 of the trunnion and is slidable transversely of the trunnion, being of vsuch length that it may pass between the lugs 26, and may be permitted to slide into engagement with one of the lugs for retaining the roller in locked position.

In order to complete the housing in which the sliding pin operates, I provide an annular element 30 having pins 31 formed thereon and adapted to be forced into the end of the roller for retaining the ring or annular element in position. Lugs 32 and 83 project from opposite sides of the ring, as shown in Figure 6, and the outer ends of the lugs pass through the apertured cap, as shown in Figure 2, and are headed as described.

In order to control the position of the sliding pin, so that it may move into engagement with the lugs 32, 3?, or out of engagement therewith, the position of the spring trunnion 22 is slightly varied by imparting a. slight rotary movement to the rod 15. This movement is entirely effected through the operating arm mounted on said roller, and because of the engagement between the slotted bracket 17 and the spring trunnion. Figures 1 and 4 show the normal position of the parts, the headed pin 2? being in engagement with lug 33. Arm or handle 16 is swung to the left (Figure 4). thereby rotating the trunnion with reference to the roller, and when the parts are in the position shown in Figure 5 pin 27 will drop through the trunnion by gravity, until its head is in the position of that view, and the pin and lugs are then free of each other,

so that the shade is wound by the action of the spring. As the result of the operation above .de-

scribed the number of operative elements is yreduced and the cost ofinanufacture -1s claimed yis :e

l. A spring controlled shade roller, including a trunnion with reference to which ,the roller isrotatable, va gravity controlled locking pin passing transversely through the trunnion, means icarried by the roller for engaging .the locking pin in one position thereof, and means for rotating the trunnion independently Aof the roller, for releasing the locking pin from said engaging means. l

2. A device of the class described, lcorn- Prsirls a roller having e longitudinal bore, a shaft mounted within the bore, a spring to be wound upon the rotation of lthe roller Aindependently of the shaft, said shaft including a trunnion having an angular'end portion, a rod extending longitudinally of the roller provided with brackets ,for mounting-'the roller, one of the brackets being slotted for cooperation with the angular ,trunnion, engaging devices rigid with refa erenceto the yen d of the roller, and a headed in one Idirection being limited ,by the head thereof. i

'3. A device of the class described, coinpri'sing a roller having Aa longitudinal bore,

a spring held ,shaft mounted within the b ore,

the roller being rotatable with reference toV the shaft, mounting means for the roller, one end of the shaft including an .angular trunnion. retained by the element of the mounting means for therollers, a pin slidable transversely through the angular trunnion, means for effecting engagement be.

tween said pin and the roller for' preventing relative rotary movement between the shaft and roller, and means for independently rotating the trunnion lfor releasing the pin. A
